Poromatosis Following Ewing Sarcoma

Amr Abduljabbar, Omar Alanazi, Amany Fathadin and Mohammad Alhaddab

Eccrine poromas are rare, benign adnexal tumors derived from the intraepidermal portion of sweat ducts. Historically they were thought to arise from eccrine ducts although today it is thought that they may also have an apocrine origin. They usually appear as solitary, slow-growing, skin-colored papules on acral surfaces. Here we present the unusual situation of a patient with multiple poromas who was previously treated with chemotherapy and radiation for Ewing sarcoma. This report adds to the increasing evidence that connect multiple poromas to some treatments of malignant conditions.
